Site to Site replication in Configuration Manager 2012


We have two types of replication in Configuration Manager.

  • Database replication
  • File-based replication

Database Replication:

  •    Global Data & Site data that replicates by using database replication.
  •    Database replication uses SQL server service broker to transfer data between the SQL Server database of different sites.
  •    SQL server service broker uses port 4022.

Global Data :-

  1. Global data objects are replicated everywhere.
  2. It consists of Package metadata, Program Metadata, Deployments, Software updates Metadata, Operating system images, Configuration Items metadata, Alert rules,Client discovery,Collections rules and count.

Site Data :-

  1. Site data objects are replicated from a primary sites to a central administration site.
  2. It consists of Alert messages,Hardware inventory,Software inventory and metering,Status messages,Status summary data,Client Health data,Component and Site Status Summarizers,

File-Based replication:

  •    File-based replication transfer the data in File format between Config Manager sites.
  •    It uses the Server Message Block protocol (Port 445).
  •    Objects are Package files,Data from secondary sites,Fallback status point state messages,Discovery data records.

Process flow :

  1. The Sending component places a file into the Replmgr’s outbound folder.
  2. Replmgr creates a job file and places it into the Ready folder.
  3. Scheduler pick up the job file and create the sending request file, and generates the compressed files, which will be sent to the tosend folder
  4. Based on the job priority and other settings, the scheduler triggers the sender to write the files from tosend folder to the despool folder on the receiving site server.
